What does vertex mean for all 3D shapes?
They are points where three or more edges meet.
How many edges meet at each vortex and does this happen to all polyhedrons?
A vortex is a form of rotating fluid flow: for example a whirlpool. A vertex, on the other hand, is a point where lines meet. There can be two or more lines meeting at a vertex: there is no limit to how many. For example, the apex of a pyramid whose base is a polygon with n-sides, will be a vertex where n edges meet (for any integer n).
How many edges of all the polyhedrons meet at each vertex?
The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.
What is same about a cube and a cuboid?
They have 8 vertices, 12 edges and 6 faces. All edges meet at right angles. All faces meet at right angles. Every face is a rectangle (a square is a rectangle). The three vertex-to-opposite-vertex diagonals meet at a point which is the centre of gravity. This point bisects the diagonals.
What are characteristics of non polygons?
it has a number of faces, vertex and edges -- The angles are not all the same
